This document discusses anticoagulation options for coronary procedures. Unfractionated heparin (UFH) is the most cost-effective option. The goals of anticoagulation are to prevent radial artery occlusion after angiography, avoid complications like stent thrombosis during percutaneous coronary intervention (PCI), and reduce bleeding. UFH 5000 IU is effective for preventing radial occlusion after angiography. For planned PCI, STEMI, or NSTEMI, UFH or low molecular weight heparin are first-line options, though bivalirudin reduces bleeding. The benefit of bivalirudin may be mitigated for radial procedures and its high cost is a limitation. More data is needed on anticoagulant
